Application filed. November 5, 1920. Serial No, f.

To all w 7mm t may concern Be it known that l, LrNcoLN R. ARNOLD, a citizen oit the United States, residing at Providence, in the county et Providence ant State et Rhode island, have invented certain new and useful improvements in Runwaye, of which the following is a speciieation.

This invention relates to improvements in portable runways of the class adapted to beV readily positioned* adjacent a curbstone lor the purpose et facilitating running a vehicle such as an automobile or the like over the curbstone either in passing from the road to the sidewall( or vice versa; and the object ot t iis invention is the provision of a pair of bridge members each haw ing one end raised to substantially the height ot the curbstone and connecting these members together by apair oi" spacing arms or bars which are ointed, whereby the members may he folded or swung together adjacent each other to reduce their storing or shipping space.

A further object ot the invention is the provision or" means whereby the working space between these bridge members may be regulated to suit vehicles having different widths.

A still further object of the invention is the provision et means whereby the height of the supporting rest bloelrs may be adjusted so that the raised end et each bridge member may be adjusted to suit curbstones of diii'erent heights.

rihe nature and advantages of the invention will be better understood when the iollowing detail description is taken in connection with the accompanying drawings., the invention residing in the combination and arrangement oit parts as claimed.

ln the drawings jorming` part of this specitication, like numerals of reference indicate similar parts in the several views and wherein Figure l is a perspective View illustrating` my improved runway in spaced apart working position adjacent a curbstone.

Fig. 2 is a. View of the underside ot the bridge members in the runway, showing the centrally pivoted connecting bars or arms in extended position.

F 3 is a detail showing one of the spring arms as connected tothe inner face of the rest bleek the arm being slotted to permit ot endwise adjustment to regulate the working space between the bridge inembers.

F ig. 1lis a side elevation illustrating the rest block as termed in two parts, one being adjustable relative to the other to regulate the working height of the raised end et the bridge member.

Fig. 5 is an end elevation of the rest block showing the same as Yformed in two parts. one ot the parts being provided with notched inclined grooves whereby one part'may be moved upon the other part to adjust the working height et the raised end et the bridge member.

Fig. 6 is a View illustrating the spacing arms as centrally piveted and folded and the bridge members swung inward adjacent each other to reduce the storing space .tor a runway and at the same time maintaining their spaced working relations when eK- tended.

Viith reference to the drawings7 l() designates the pair of bridge members which may be made of suitable material but which l' preferably maire ot wood,\the same being` ot any desired width and et suitable length to provide a proper angle tor eonductingan automobile up over the edge of a curbstone l1.

@ne end l2 of each bridge member is adapted to rest upon the ground while the opposite end is provided with a suitable rest block 13 for raising and supporting this end at the height of the curbstone 1l.

These bridge members are spaced apart and held in proper working` position by means oit a pair ot arms or ears A, one end oi" each being` connected to the inner tace ot the rest block while the 'free ends ot these arms or bars are pivotally jointed or hinged together preferably by a pivot bolt 15, which bolt also passes through the ends of' a handle 1G by means of which the device may be readiiy carried about in the hand ot the user and then hung` up in a convenient place in a garage or barn.

in some instances it is found of advantage to be able to adjust the working length ot the connecting arms or bars to accommodate vehicles et diderent widths. To accomplish this in a simple and practical way I have slotted the ends 17 of the bars 1A at 18 longitudinally whereby by loosening the bolts 19 these arms may be adjusted endwise to regulate their working length.

In still other cases it is found to be of advantage to be able to adjust the rest block so as to regulate the working height of the raised end of the bridge member to accommodate curbstones of different heights.

To accomplish this in a simple and practical way, I have formed the rest block in two parts as illustrated in Figs. 4 and 5, one of the parts 20 being provided with inclined slots 21 the upper edge of which slots are notched as at 22, which notches are engaged by the pins or bolts 23.

. By this construction it will be seen that the notches in the edges of these slots serve to engage the pins or bolts 23 and so lock the parts in adjusted position against movementregardless of any strain or weight they v may be called upon to withstand.

My improved runway is extremely simple and practical in construction and by its use the bridge members are held in proper spaced apart relation and yet when not in use the whole may be folded into a contracted space to facilitate shipping and storing; then again by this construction the spacing distance between the members may be readily adjusted to suit vehicles of different widths; also the operating heights of the bridge members maybe readily adjusted to accommodate different heights of curbstones.

The foregoing description is directed solely toward the construction illustrated mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appendedA claims.

I claim:

1. A runway comprising a pair of spaced apart short inclined bridge members each having'a rest block at one end for supporting said end the height of a curbstone, and a pair of foldable spacing arms or bars con-V necting said members whereby said members may be positioned adjacent each other.

2. A runway comprising a pair of spaced apart short inclined bridge members each having arest block at one end for supporting said end the height of a curbstone, a pair vrest block may be regulated.

7.4. A runway comprising a pair of spaced apart short inclined bridgeY members each having a rest block` at one end for supporting said end the height of a curbstone, said block being formed in two parts one being provided with `notched inclined slots by which said parts may receive relative ad-` justment for regulating the working height of said block, and a pair of foldable spacing arms connecting said bridge members whereby said members may be positioned adjacent each other.

In testimony whereof I afiiX Vmy signature.
